--><p><i>Potentilla robbinsiana</i> is known only from two sites in the White Mountains, Monroe County, New Hampshire, and is reported in Vermont. Additional populations have been established nearby as a result of transplant efforts. Listed in 1980 as a federally endangered species, an intense recovery program resulted in the species being delisted in 2002.</p><!--
--><p>Some early specimens were distributed as <i>Potentilla</i> frigida Villars, a similar European species.</p>
